Global Market: Japan's Nikkei extends rally on AI boost, but US-Iran impasse weighs

Nevertheless, the progress in US-Iran discussions and ongoing market fluctuations dampened this rally. Companies like Sumco and Taiyo Yuden experienced substantial rises, hitting remarkable new peaks. While manufacturers are feeling more optimistic, challenges like escalating costs and supply chain disruptions remain worrisome.
